Broadest Luer Selection Online

120+ luer configurations

Available in nylon, polypropylene, polycarbonate, polyvinylidene fluoride (PVDF), and other materials by special order

Luer Locks & Luer Slips

The two main categories of luer fittings are luer locks and luer slips:

Luer-lock connectors (female) are joined by means of a tabbed hub on the female fitting that screws into threads in a sleeve on the male fitting and attaches securely. Male luer lock connectors are available with integral lock rings or with rotatable features to allow you to position the tubing before assembly. This locking mechanism is used for applications that require a secure connection.

ISO 594-1 Standard Luers

Our luers conform to the ISO 594-1 standard of a 6% taper and connect to other standard luers. If your application requires mating components from other suppliers, please test the performance of the interconnection, as other manufacturers' products may not meet the international standard.
